# Using the average atomic masses given inside the front cover of the text, calculate the mass in grams of each of the following samples.l type='a'>5.0 moles of nitric acid0.000305 mole of mercury   2.31 × 10 − 5 mole of potassium chromate10.5 moles of’ aluminum chloride   4.9 × 10 4 moles of sulfur hexafluoride1 25 moles of ammonia0.01205 mole of sodium peroxide

Interpretation Introduction

(a)

Interpretation:

Mass in grams of each substance the following moles represent should be calculated.

Concept Introduction:

The molar mass, also known as molecular weight, is the sum of the total mass in grams of all the atoms that make up a mole of a particular molecule.

Molar mass=Mass of the sample in gramsNumber of moles

Mass of the sample in grams = Number of moles × Molar mass.

Explanation

Molar mass of HNO3 = {1.008 + 14.01 + (3 × 16.00) g/mol = 63

Interpretation Introduction

(b)

Interpretation:

Mass in grams of each substance the following moles represent should be calculated.

Concept Introduction:

The molar mass, also known as molecular weight, is the sum of the total mass in grams of all the atoms that make up a mole of a molecule.

Molar mass=Mass of the sample in gramsNumber of moles

Mass of the sample in grams = Number of moles × Molar mass.
